The production of heavy quarks has been studied with the ZEUS detector using an integrated luminosity of 136pb-1 from the 2004 to 2005 e-p running of HERA-II. Charm and beauty production has been measured by looking at the semi-leptonic decays to electrons of heavy hadrons which is done for the first time at HERA-II, using a new analysis technique of a maximum likelihood method to estimate the number of electrons. The visible cross section in the kinematic range 5 < Q2 < 1000 GeV2 , 0.02 < y < 0.7, pe > 1 GeV and Iryel < 1.1 has been measured as well as differential cross sections in Q2, x, Pr and 1]e. The cross sections were compared with NLO QCD calculations, and agreement was found for all the variables apart from 1]e. Cross sections were also measured in (Q2, y) bins allowing measurements of F2cC to be made, which were compared to the ZEUS NLO PDF fit and found to be generally in agreement.
